These buses use the motorway, and do no stop in Galway city.
Timetables are still to be released, but services can be booked on their website now and it looks like they are running:
- Two buses on Friday from Limerick to Letterkenny (and maybe beyond)
- One bus on Sunday from Letterkenny (or further) to Limerick
Journey time is approx 5 hours.
Although these buses run on days + times that will suit students, they can be used by anyone who wants to travel.
